Products.MailHost 5.0

Usage

MailHost provides integration with the Zope transaction system and optional support for asynchronous mail delivery. Asynchronous mail delivery is implemented using a queue and a dedicated thread processing the queue. The thread is (re)-started automatically when sending an email. The thread can be started manually (in case of restart) by calling its manage_restartQueueThread?action=start method through HTTP. There is currently no possibility to start the thread at Zope startup time.

Supports TLS/SSL encryption (requires Python compiled with SSL support).

Configuration

To force MailHost to only queue mails without sending them, activate queuing in the ZMI and set the environment variable MAILHOST_QUEUE_ONLY=1. This could be helpful in a staging environment where mails should not be sent.
